Ore dake Level Up na Ken

Both shows have a similar, gamified world setting (in SAO it's literally a video game, in Solo Leveling it's game-like system brought to real world). Both protagonists Kirito and Jin-Woo are similar in some way, and both are overpowered individuals and are lone wolves. If you like one of these, you might like the other one. 

Strong power fantasy world, in both cases the protagonist is very strong by himself, and with pure action scenes stand out as exemplary. 

If you liked the first season of Sword Art Online u would definitely like Solo Leveling. This anime is from a manwha that is very famous and it is incredible. It only has one season and is not the best season ever but it is a very good season. It is very enjoyable thanks to an amazing soundtrack, a very good animation and top figths. So i definitely recommend u Solo Levelijng, Im sure u would like it. 

A-1 Pictures anime adaptation of a very popular series that involves a male protagonist who manages to become an overpowered badass. Featuring excellent action sequences that are enhanced by an excellent soundtrack. 

Solo Leveling and Sword Art Online are two series I’ve really enjoyed, and they have a lot in common that makes them stand out. Both stories create immersive worlds where characters level up through intense battles. Sung Jin-Woo and Kirito both start as underdogs but undergo incredible transformations, which makes their journeys so satisfying to follow. One thing I love is how they highlight teamwork and friendships. Both protagonists build strong connections with others, which adds depth to their adventures. Plus, the action scenes are thrilling and strategic, keeping me on the edge of my seat. Even though Solo Leveling leans into darker fantasy elements and Sword Art Online focuses on virtual reality, they both capture themes of growth and resilience beautifully. If you’re looking for an exciting read or watch, either series won’t disappoint! read more 

Both Anime's show great proggression thru the main characters where both follow almost the same path to success 

While one takes place in the modern world and the other is in a medieval setting, both share their intense dungeon crawling experience, characters often fighting for their lives just to survive and make ends meet. The main characters of both shows have a unique ability related to their leveling up that is integral to the stories both try to tell. The action scenes in both are also often pretty well animated, which is just another plus. 

the storyline is pretty a weakling that was very stubborn and the potential to level up quickly the struggling rooking turned strong 

About a guy in dungeon who tries to get stronger. Very similar plots but execute it differently.  

Both feature a protagonist who is weak at first and gets ridiculed for it, but then goes through a traumatic experience that makes him want to become stronger. They also have similar personalities, they're independant and cunning and can be ruthless at times to serve their own interests. Both shows also rely heavily on the incorporation of video game mechanics, like a lot of isekai do, but there's an attempt to "subvert" the tropes of the genre by adding plot twists or making the protagonist more morally grey. They're both entertaining enough but not all that deep. 

Both animes are based on the concept of a gate to another world, dungeons, and monsters. 

This anime has similarities such as having subordinates who are loyal to their orders. In addition, in the story there are always developments from time to time. The only difference is in the concept where Overlord Isekai Game and Solo Leveling must start the journey from scratch to get subordinates. 

Both series' protags are initially weak but exploit the system in their own ways to get stronger and beat strong opponents. Both series use video game systems extensively: SLF is an actual game and has strong and relatable game mechanics, while SL uses the tried and true video-game-dialog magic system typically seen in fantasy reincarnation shows. Shangri-la Frontier focuses more on character- and world-building than Solo Leveling, while the latter focuses more on the power fantasy angle. 

It's very similar in terms of how each get stronger as it goes on and both have that Isekai vibe, I know anyone who watches this will absolutely love it! 

both are set in a modern world where fantasy dungeon opened up although some time has past and the dungeon are part of the economy both have MCs that begin the series extremely weak both get more powerful in the first few episodes and try to keep it secret
